Nimbia is a common enigmatic discoidal form from Neoproterozoic, possibly into the Cambrian, and can be found from across the globe. Most researchers consider them to either be simple microbial colonies, equally simple cnidarians, or the holdfasts of a larger organism, such as those seen in the Petalonamae phylum.
